APPARATUS FOR LOADING OR UNLOADING VESSELS.

SPECIFICATION formingpart of Letters Patent No. 747,923, dated December 29, 1903.

Application filed September 18,1902L Serialllo.123,893.` (No model.)

To all whom it may concern:

Be it known that I, GEORGE HENRY AIEEY, a subject of the King of the United Kingdom of Great Britain and Ireland, residing at 3 Rue Cernuschi, in the city of Paris, France, have invented new and useful Improvements in Loading or UnloadingVessels,'of which the following is a specification. w

This invention relates to improvements in loading and unloading vessels, and in carrying it into effect I proceed in or in about the following` manner, making reference to the accompanying drawings, wherein- Figure l is a side view of the arrangement on the delivering vessel; Fig. 2, a front view Vof part of Fig. l; Fig. 3, aside View of the arrangement on t-he receiving vessel; Fig. 4, a side view, and Fig. 5 a front view, of-a hook to be hereinafter described; and Fig. 6, a general View of the arrangement on the deliverlng and receiving vessels. Figs. 7, 8, and 9 are, respectively, side, front, and plan views of details to be hereinafter mentioned.

On the delivering vessel a, I provide amast b, having running on or within it a Weight c, to which is attached one end of a wire rope or the like d, which passes over a pulley e and then through a sloping tube f, from whence it passes to and under a pulleyg on the deck h of the receiving vessel, and this, pulley may be removable,r so that it can be placed at any convenient part of the deck, The wire rope d is continued over a pulley or guide at the top of a suitably stayed mastj on the receiving vessel and is finally attached to a Weight lc, running on or within the said mast j.

At the top of the mast bis a pulley or drum I Z and at the bottom is a similar pulley or drum fm. Over the said pulleys or drums l and m ispassed an endless band n, the pulleys being at right angles to the pulley e and tube f, and guides may be provided to keep the band n in place as it passes along.

A chain or other contrivance may be used instead of a band, and the drums Zand m may be replaced by sprocket or polygonal wheels.

The drum m is rotated by any suitable motor or by hand.

Outstandingfrom the band n are a number of guard-arms o, each curved toward the opposite side of the band to` that towhich they are attached, and adjacentl to each pair of the arms o is a carrier p, to each of which is detachably attached a bag q of the article being loaded or unloaded. The bags-q are suspended from hooks r, having the downwardlysloping releasing-arms s and an elevatinghook t, which is placed on the carrier p. The guard-arms o and carriers p areattached to the band n by sockets r', riveted to the belt fn.

It is essential to the steady conveyance of the goods that the hook t should be long and flat, so as to re'st firmly on the carrier p, the .bags being kept from swinging outward by the above-mentioned rods 0.

Betweenthe highest part of the releasing hook fr is a pulley u for facilitating the movement of the hook r, as will be presently described, and a snap-hook may be provided some distance below the hook r to keep the hook from running od.

The operation is as follows, assuming the band n to be revolved by any suitable means: The bags of material q are suspended from the carriers p by the hooks t in such manner that the downwardly-sloping arms s shall be inside the band n, when the bags are being raised. When the pulleys u come in contact Y with the sloping tubef, (into which position they are guided by the sloping arms 5,) the bags q are lifted from the carriers p and the pulley u put on the tube f, whereupon the hook and bag q Will run down lthe wire ol and carry the goods to the receiving vessel. If desired', the weights c and la can be allowed to run overboard or down a stay and, if preferred, multiplying tackle can be used, so as l to provide for a longer wire cl. The mast b may, if preferred, be erected on a quay or- In means for loading and unloading vessels wherein the goods are run down an inclined rope from the delivering to the receiving Vessel, an endless-band elevator; lifting-arms outstanding from the said endless band; an
